高圧ホース

Application
High-pressure hoses are used for energy and signal transmission in hydraulic systems. Especially when connecting movable elements, but also for the connection of hydraulic subassemblies which are not fixed on a common base, e.g. power units and clamping fixtures. 

Hose structure 
Depending on operating pressure and nominal diameter, high-pressure hoses consist of one or several layers of wire or textile mesh or spiral inlays.
1: Inner tube
2: Inlay
3: Cover
4: Hose wall
5: Insulation layer

Hose connection
After pressing of the hose fittings at both ends the high-pressure hose is ready for connection.
1: Hose
2: Nipple
3: Holder
4: Union nut
5: Hose fitting

Service life / installation instructions
The application time including storage time should not exceed 6 years, the net storage time 2 years.High temperatures, frequent motion cycles or high pulse frequencies can reduce the application time.

Maintenance
Before putting into operation and then at least once a year, the high-pressure hoses have to be checked by an expert if they are still leak-proof.

Marking hose
on the hose there is the following marking:

• name or code of the manufacturer
• number of European standard
• type
• nominal diameter
• quarter and the last two figures of the year of manufacture

Marking fitting
on the fitting there is the following marking:

• name or code of the manufacturer
• month of manufacture
• the last two figures of the year of manufacture
• nominal pressure PN of the hose fitting
• part number of the complete hydraulic hose

Important notes
We deliver only completely pressed high-pressure hoses with mounted union nut.Pipe sockets with removable cutting ring and union nut are no longer allowed.
